In David Tong's notes on the quantum hall effect, when calculating the current due to edge modes, he writes it's expression as. Iy = −e ∫ dk 2πvy(k) I y = − e ∫ d k 2 π v y ( k) where vy v y is the drift velocity of the state with momentum ℏk ℏ k. But I fail to understand how that gives the current.4.3.4 There is a Subject Called Topological Quantum Computing 145 5.
